BTW - I just thought of another reasonable & cheap method to get good water ... collect rain water. If you have a place where you can collect rain water, and your city is not too polluted (acid rain, smog, other pollutants), then rain water is a viable source for the tank. You will have to add the buffer salts (& other ions for your plants/inverts), but sure beats lugging expensive water home from the lfs!
